How to data store any added values in a table

i dont know if i was clear in the caption but heres what i want

i want to data store any added value to a table
such as when i send a value to the server from the client it saves it and when i send an another value it also saves (the values are unknown its just ANY value sent) , and when the player joins the game again it displays that data to the client lets say with a print(data) from client

any help will be appreciated (btw i dont have any scripts)
